Question

Determine the measure of x, to the nearest tenth of a degree.

Answer 1

About 73 degrees

Explanation:

By the law of cosines:

`26^2=11^2+27^2-2(11)(27)\cos(x) \\\\\\676=121+729-594\cos(x) \\\\\\-174=-594\cos(x) \\\\\\\cos(x)= 0.\overline{29} \\\\\\x\approx 73.0^(\circ)`

Hope this helps!
